Parking at the Cascade car park: take Rue du Gazon Vert from Stockenson and follow the signs towards Gazon Vert; the road is tarmac for about 2 km, the rest of the route is passable at low speed.
(S/E) From the Cascade car park, follow the red and white rectangular signposted trail which crosses the pasture to the Natura 2000 sign marking the start of the walk.
(1) From the sign, take the waterfall path, which offers a view of the waterfall and continues through the forest. At the first junction, turn right; at the next, follow the signs for the Gazon Vert nature trail. Continue climbing to the right through the forest.
(2) At the crossroads, where the circular path begins, at the top of the waterfall, leave the path (Red Rectangle and White Rectangle) on your left, which will be your return route. Head right towards the footbridge.
(3) Cross the metal footbridge, then take the path running alongside the pasture wall. Leave the forest and take a path that climbs above the stubble. Continue the climb to a bench and a viewpoint.
(4) Head back down along the wall and turn left at the crossroads (marked with a Yellow Triangle) towards the Vieille Ferme.
(5) Walk past the farm across the Gazon Vert scree slope. Follow the signs for “Auberge du Gazon Vert” and pass beneath the glacial scree on the path marked with a Yellow Triangle before entering the forest. In the forest, leave the Yellow Triangle path which climbs to the right and continue left towards the inn.
(6) In front of the inn, head down through the pasture to the forest. The path, marked with red and white rectangles, heads north and joins the top of the waterfall and the junction of the circular path.
(2) Head down to the right at the foot of the waterfall and continue along the same path as on the way up to the car park (S/E).
